[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize ball discharging device in a pachinko game machine, and more particularly, to a pachinko game machine capable of developing a pachinko game in a game board, wherein a pachinko ball stored on the back side of a pachinko game machine is used. While the ball can be paid out to the ball plate side as a prize ball for winning, the ball can be pulled out of the machine as a return ball (return ball) by a ball release operation,
The present invention relates to a prize ball discharging device that prevents illegal removal of a stored ball extracted as a return ball.

[0002]

2. Description of the Related Art In this type of gaming machine represented by a pachinko machine and an arrangement ball machine, a ball is fed from a ball plate to a firing position by a ball-feeding / launch control operation for each ball started based on a game operation. The required pachinko game can be played by launching the game ball into the game board. Then, the balls stored in the ball storage and discharge path section on the back side of the machine are paid out by the prize ball payout device in response to the winning conditions during the game (such as generation of a safe ball and establishment of a symbol combination score by entering the ball). Each operation is paid out as a predetermined number of prize balls, and is supplied to the upper and lower ball dishes from a predetermined prize ball path. On the other hand, when it is necessary to remove a considerable amount of stored balls in the ball storage / discharge path due to handling of the gaming machine, generally, an operation rod is inserted from an operation hole formed on the front side of the front frame to insert the operation rod. With the switching valve provided at the branch connection between the prize ball path and the ball-extraction path held in the ball-extraction state (ball-return position), the stored From the outside of the aircraft. The operating rod is a wire-like material having a knob, and is managed by the hall manager. However, a straight material that is easily available can be sufficiently substituted.

[0003] In such a pachinko gaming machine, apart from paying out prize balls, as a form in which all stored balls can be paid out by a ball removing operation, the prize ball payout device generally uses an electric motor for each winning condition. Tools (solenoids and motors)
The electric drive type that pays out and counts the prize balls while controlling the rotation of the ball feeder facing the ball path by the drive control of the ball is used. In the ball punching device, the detection input of the switch operated by the operation rod is used. An electric type is used in which the switching valve is switched to a ball release (return) position to be held and pulled out by drive control of an electromagnetic solenoid based on the above. And as an embodiment of both devices, at the side edge of the mechanism set board on the back side provided with a window for game board inspection, a prize ball payout device is installed in accordance with the downstream portion of the ball storage and discharge path section,
Further, a ball-pulling device is installed at a branch connection between the ball-pulling path and the ball-pulling path communicating with the downstream of the ball-pulling-out device, and based on the detection input of the switch in the ball-pulling operation, the switching of the switching valve and the prize. Under the condition for releasing the ball dispensing device, all the withdrawn balls can be released.

[0004] In addition to the operation rod, the ball punching device can detect a switch operation by a fingertip operation on the back side of the front frame opened from the outer frame.
Also, in both devices, as a ball-pulling control process in the electronic control device, the detection input of the switch is enabled only once,
After the ball release operation, the power is turned on again or a reset input operation related to the electronic control unit is performed as a normal restoration process. Unless this processing is performed, the subsequent detection input of the same switch is invalidated and the ball is set to be impossible to remove. Under the circumstances, the electric tool and the electromagnetic solenoid are set so as to automatically return after a predetermined time elapses based on a timer setting condition in the electronic control device with respect to the detection input of the switch for removing the ball.

[0005]

The prize ball dispensing device is installed at a required portion downstream of the ball storing and discharging path, and the ball removing device is disposed immediately adjacent to the downstream portion of the prize ball dispensing device. It is installed, and the respective devices cooperate with each other in close relation, so that the stored ball can be paid out to the upper ball tray or the lower ball plate side as a prize ball, or can be withdrawn outside the machine. However, despite these prize ball payout devices and ball punching devices being installed vertically and being controlled in conjunction with each other, they are individually designed and manufactured as separate devices, The disadvantage is that the production cost increases. Also, when the prize ball dispensing device and the ball punching device are connected vertically, it becomes quite large, so on the mechanism set panel, a large installation area must be secured based on the external size of both devices. In addition, the design of the entire prize ball discharge path was subject to some restrictions. Further, in the assembling work on the mechanism set board, since the prize ball payout device and the ball removing device must be separately positioned and set and installed, the assembling becomes troublesome and takes time, and the assembling of the gaming machine is performed. This has been an obstacle in reducing costs and rationalization of the above.

In recent years, in response to the demand for pachinko gaming machines, in addition to paying out the stored balls on the back side of the machine as prize balls, it has been demanded that they can be paid out as rental balls for games.
In many cases, the above-mentioned electric type prize ball payout device is used, and the ball punching device is incorporated in the lower part correspondingly. In such an embodiment, it is easy to separately pay out the prize balls and the rental balls, and even if all the stored balls can be withdrawn, the illegal extraction acquisition of the stored balls is permitted. There was a big problem. That is, in the present situation, the ball-pulling switch is easily operated and detected even with a wire-shaped material other than the operating rod, and based on this detection input, both devices are operated in a ball-pulling state and a ball-pull-out state. You. For this reason, a fraudulent person familiar with the configuration of the gaming machine and the form of both devices, etc., intrudes into the prize ball path from a supply port for communicating a linear fraudulent object to the upper ball dish in a posture pretending to be a normal game. Then, while skillfully manipulating, the switch valve is inserted into the upper side of the ball removing device to hold the switching valve in the dispensing position. In this case, when the switch is illegally detected and operated, all the stored balls are discharged from the prize ball dispensing device in the ball release and released state, and then discharged to the prize ball path by the above-described switching valve. It is fed to the upper or lower bowl.

Accordingly, in many pachinko gaming machines equipped with the above-mentioned electric-type prize ball dispensing device and ball removing device in combination, all the stored balls are out of the machine by a normal ball removing operation. Although it has a convenient function of being able to pull out the ball, it has an inherent disadvantage that it can be obtained by illegal ball pulling as described above, and this cannot be prevented suitably. As a result, even if only the illegal withdrawal by one effective detection operation of the switch is permitted, hundreds of stored balls are actually withdrawn, and if the number of gaming machines increases, the quantity that can not be neglected at all ( There was a problem that the hall side was seriously damaged due to the storage ball of (amount). By the way, the illegal ball removal mentioned above is performed skillfully without even the neighboring player noticing, and the hall side seems to detect abnormalities after checking the operation status of each unit by computer management It is in the current situation.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been proposed to solve the above-mentioned problem suitably, and a ball dispensing operation for dispensing a ball in one case set on a mechanism set board on the back side of the machine. Unit, and a switching discharge unit for performing a ball discharge switching operation so as to reduce the size and simplification of the entire device and to simplify the implementation (assembly) on the mechanism set panel, and In the pachinko game machine, the switching discharge unit is not allowed to be held in a ball dispensing state by a malicious artificial operation aiming at fraud, so that it is possible to prevent the acquisition and acquisition of the stored ball by an illegal ball-pulling action from the front side. It is intended to provide a prize ball discharging device.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to achieve the initial object, the present invention relates to a method of storing a stored ball in a ball storage / discharge path section of a mechanism set board mounted on the back side of a machine in a game board. A pachinko gaming machine that pays out as a prize ball for the winning of the pachinko game and feeds it from the prize ball path to the ball tray side, while pulling out as a return ball by a ball pulling operation and discharging from the ball pulling path to the outside of the machine, An electrically operated ball dispensing unit capable of dispensing the stored balls one by one into a case body which is detachably attached to a required portion of the mechanism set board and has a ball passage formed therein, and dispensing from the ball dispensing unit; An electric switching and discharging unit capable of switching out and out of the drawn ball to the prize ball path side and the ball-pulling road side is incorporated into the case body unit, and the case body is provided downstream of the ball storage / discharge path section. Below the ball entrance that communicates with In addition, a payout path communicating with the prize ball path and a return path communicating with the ball removal path are formed, and in the ball payout section, a rotary ball feeder supported at a position facing the ball entry path may be appropriately provided. It is configured to control rotation stop by an electric tool driven by the control of the electronic control unit to pay out one ball at a time, and in the switching discharge unit, a switching valve supported at a branch communication portion of a payout path and a return path, While being configured to be able to switch and hold between the payout position and the return position by an electric tool driven by control of the electronic control device as appropriate,
Under the condition that the maintenance switch detects the switching valve at the return position in the ball removing operation, the ball dispensing unit is enabled to perform the dispensing release operation, and under the condition that the maintenance switch does not detect the switching valve displaced to the dispensing position side. The dispensing release operation of the ball dispensing section is disabled, and the ball dispensing section is set so as to prevent withdrawal of the stored balls to the dispensing road side.

[0010]

In the case body formed with a ball entrance path communicating with the ball storage / discharge path section, a payout path communicating with the prize ball path, and a return path communicating with the ball removal path, rotation stop control is performed by the electric tool. A ball dispensing section having a rotary ball feeder is disposed at a position facing the ball entry path, and a switching discharge section having a switching valve switched and held by another electric tool is connected to the dispensing section and return path. And the prize ball discharging device can be handled as one unit member that is reduced in size and simplified by incorporating the ball discharging portion and the switching discharge portion in the case body. Therefore, when assembling to the mechanism set board, the case body can be easily and easily installed at a predetermined position on the downstream side of the ball storage / discharge path simply by positioning and setting the case body and fixing it with screws or the like. Work can be simplified and streamlined.

In the switching discharge section, when the switching valve is displaced to the return position, the maintenance switch is detected (ON).
Then, the ball dispensing section is controlled to the dispensing release operation state under the detection condition of the maintenance switch, and dispensing of the stored balls is performed. Therefore, since the switching valve is held at the return position, the stored ball discharged from the ball discharging section is discharged to the outside of the machine from the ball ejection path after being guided to the return path side. On the other hand, when the switching valve is displaced toward the dispensing position, the maintenance switch is in a non-detection (OFF) state, and under the non-detection condition of the maintenance switch, the ball dispensing unit is controlled to be in a dispensing release inoperable state, and the storage ball is disengaged. Is stopped. Therefore, even if the switching valve held in the return position is forcibly displaced from the return position to the payout position side by an illegal operation, the payout itself of the stored balls in the ball payout section is stopped, so Is prevented from being illegally withdrawn to the payout road side.

In the pachinko machine of the present embodiment configured as described above, the pachinko machine is installed together with the card unit E on an installation frame in a game hall and can be used for games. Then, by inserting a card into the card unit E and lending the ball on the front side of the machine, the lending ball dispensed from the prize ball discharging device F of the mechanism set board C can be supplied to the upper ball plate side and accommodated. By performing a game operation (hitting ball firing operation) under this condition, the game balls sent one by one to the launch position in the machine can be launched into the game board to develop a required game. Then, the out ball generated during the game is discharged from the discharge path 2 of the mechanism set board C to the outside of the machine, and the safe ball is introduced into the safe ball detection processing device D from the processing path 3 to detect the stop of each ball one by one. After the processing, the ball is ejected out of the machine, and in response to the safe ball detection processing, a set number of prize balls are paid out from the prize ball discharging device F and supplied to the upper ball dish or the lower ball dish. Then, the ball stored in the ball storage / discharge path section 4 can be
With the prize ball discharge device F released, the ball can be extracted and discharged from the ball extraction path 9 to the outside of the machine.

The ball discharging operation state of the prize ball discharging device F of this embodiment implemented in such a pachinko machine will be described with reference to the drawings. First, with respect to the payout of the lent ball, the ball payout unit 35 is operated based on the ball inserted switch 11 for the lent ball switch 11 and the ball lending switch 59 being operated under the ball presence detection input condition. You. That is, based on the control processing between the card reader 23, the interface board 24, and the second electronic control device 22 in response to the operation input of the switch 59 and the ball lending command, the ball payout unit 35 is operated to control the electromagnetic solenoid 39. Operation (excitation and demagnetization) and restriction piece 41
Is switched, the ball presence detection input of the first and second detectors 43 and 44 and the pitch rotation of the ball feeder 37 cause a predetermined number of balls.
(For example, 25 lending balls for 100 yen lending amount) is 1
The balls are paid out one by one, discharged from the payout path 30 of the case body 26 to the first prize ball path 5, and supplied from the supply port 6 to the upper ball plate. Looking at the specific state of discharge of the lent balls in FIG. 5, all the lent balls are counted and detected by the second detector 44 after being released from the receiving portion 38 of the ball feeder 37, and are discharged to the payout path 30. Switching valve 5 which is inserted and kept at the dispensing position
2 and is discharged to the first prize ball path 5.

As to the payout of the prize ball to the safe ball, the ball payout section 35 is activated every time the safe ball is detected by the safe ball detection processing device D shown in FIGS.
That is, under the condition that the switch 17 detects a safe ball that has passed through the processing path 3 into the path 16 and has been stopped at the detection position by the stopper 18b of the regulating processing member 18,
The second and first electronic control units 21 and 22 for the detection input
On the basis of the processing of the safe ball signal and the prize ball signal and the payout command, the ball payout unit 35 is operated in the same manner as described above (see FIG. 5), and the control operation of the electromagnetic solenoid 39 and the restriction piece 41 are performed. A predetermined number of balls (for example, 5 to 15 prize balls) are paid out one by one by the pitch rotation of the ball feeder 37 according to the switching of the first prize ball path from the payout path 30 via the switching valve 52. 5 and is supplied from the supply port 6 to the upper ball dish or from the second prize ball path 7 to the lower ball dish. Then, based on the point in time when the predetermined number of the last awarded balls that have been paid out are counted and detected by the second detector 44, the payout operation of this time is terminated, and the ball is fed according to the demagnetization of the electromagnetic solenoid 39 and the return of the regulating piece 41. The body 37 is stopped and held. After the payout is completed, the safe ball detection processing device D receives the electromagnetic solenoid 19 based on the safe ball release command from the second electronic control device 22.
Is operated once (excitation and demagnetization), the safe ball at the detection position is released according to the switching of the regulation processing member 18, is discharged out of the machine, and the next safe ball enters the detection position and stops ( (See FIG. 3).

On the other hand, in the case of removing the stored ball, the switching discharge section 47 and the ball payout section 35 are sequentially operated based on the ball removing operation. In other words, when the switch 14 for ball removal is operated, the switching discharge unit 47 is switched based on the control processing in the second electronic control unit 22 for this detection input and the command for ball removal, and the electromagnetic solenoid is operated. As the rod 49 rises due to the excitation of 48, the switching valve 5
2 is switched to the return position and held (see FIG. 6). And
When the rotating cam 54 presses the switch button 66 of the maintenance switch 65, the maintenance switch 65 is turned on.
Under the condition that the switching valve 52 is detected in the state, for example, after 1.5 seconds, the ball dispensing section 35 is opened, and the restricting piece 41 is magnetically displaced by the excitation of the electromagnetic solenoid 39 so that the ball is displaced. The feeder 37 is released. As a result, as the ball feeder 37 continuously rotates freely while receiving the ball in the ball entrance 28 of the case body 26, the stored ball in the ball storage / discharge path section 4 becomes as illustrated in FIG. Payout path 3 for each ball
It is discharged to 0 and is guided to the return path 31 while being diverted and guided by the switching valve 52, and is withdrawn from the ball-extraction path 9 to the outside of the machine. Then, at the end of the ball removal command after the elapse of the set time, the ball dispensing section 35 is returned to its original state, the demagnetization of the solenoid 39 causes the regulating piece 41 to return to its displacement, and the ball feeder 37 is stopped and held. Subsequently (for example, after 3.5 seconds), the switching discharge unit 4
7 is returned to its original state, and the switching valve 52 is lowered to the original dispensing position (FIG.
2). At this time, the rotating cam 54 is separated from the switch button 66, and the maintenance switch 65 is turned off.
In the F state, the switching valve 52 is not detected.

In the above-described ball removing operation, even if a slight ball flow delay occurs in the ball storage / discharge path section 4, the entire ball can be accurately removed by setting the excitation time of both solenoids 39 and 48. . And after removing the ball,
By operation of the replenishment equipment, a new considerable amount of balls are stored in the ball tank 4a
The ball entrance 2 of the ball payout section 35
The ball is passed (accommodated) from a predetermined position (the position at which the ball feeder 37 is received) in the ball storage / discharge path 4 so that the above-mentioned rental ball and prize ball can be paid out. Incidentally, the second electronic control unit 22 according to the prize ball discharging device F of the present embodiment.
As another setting example, the ball lending operation signal can be input after the prize ball payout command is completed, and the ball lending operation signal is disabled (invalid) after the ball removal operation signal is input. The prize ball payout signal can be input after the end of the ball lending command, and is disabled (invalid) after the input of the ball removal operation signal. In addition, the ball-pulling operation signal is set to 1 after the end of the instruction to pay out the lending ball and the prize ball.
Valid input is allowed only once.

By the way, in the prize ball discharging device F of this embodiment,
In addition to being able to perform the above-described ball discharge operation, it is also possible to prevent the illegal acquisition (removal to the upper ball plate side) of stored balls to be discharged outside the machine by a ball removal operation as a unique function of the device, Regarding this preventive measure, it is possible to detect and operate the ball release switch 14 with an operation rod inserted from an operation hole (both not shown) of the front frame B to hold the switching discharge portion 47 in the ball release state. Even if a fraudulent object is intruded from the supply port 6 to the back side by a fraudulent operation on the front side of the machine and skillfully manipulated, it is possible to preferably prevent the stored balls from being discharged to the payout path 30 side. That is, before the ball discharging operation of the prize ball discharging device F, the switching valve 52 is displaced to the oblique payout position and the rotating cam 54 is separated from the switch button 66 as shown in FIG. , Maintenance switch 6
The condition in which the switch 5 is turned off and the switching valve 52 is not detected is input to the second electronic control unit 22. Therefore, the ball dispensing section 35 is controlled to be in a dispensing release disabled state by the non-detection condition of the maintenance switch 65, and the dispensing solenoid 39 is controlled to be stopped.

When the ball release switch 14 is operated by the operation rod inserted through the operation hole of the front frame B, the switching electromagnetic solenoid 48 in the switching discharge section 47 is excited to follow the upward displacement of the rod 49. As a result, the rotating cam 54 rotates, and the switching valve 52 is switched to the upright return position and held. When the rotary cam 54 presses the switch button 66 of the maintenance switch 65, the maintenance switch 65 is turned on and the ball dispensing section 35 dispenses under the condition that the switching valve 52 is detected. In the release operation state, the dispensing solenoid 39 is excited and the dispensing of the storage sphere is started appropriately after the start of the operation of the switching solenoid 48 (see FIG. 12B). At this time, since the switching valve 52 is held at the upright return position where the payout path 30 is closed and the return path 31 is opened, the stored balls discharged from the ball payout section 35 are moved to the return path 31 side. After being guided, it is pulled out to the ball pull-out path 9 (see FIG. 12 (b) and FIG. 13).

Then, in the state where the stored spheres are withdrawn as shown in FIG. 12B, the linear illegal object 61 is caused to enter the first prize ball path 5 from the supply port 6 and to be inserted into the payout path 30 side. And the unauthorized object 61 is switched along the outer circumference of the bell 62 by the switching valve 5.
2 and the switching valve 52 swings clockwise in the figure. As a result, the switching valve 52 held at the upright return position slightly swings and displaces against the exciting force of the electromagnetic solenoid 48, as shown in FIG. Since the rotating cam 54 also rotates,
Pressing of the switch button 66 is released. That is, since the maintenance switch 65 is turned off, the ball dispensing section 35 is turned off under the condition that the switching valve 52 is not detected.
Is disengaged, the dispensing solenoid 39 is demagnetized, and the dispensing of the stored balls is stopped.
Therefore, as shown in FIG. 14B, even if the switching valve 52 is forcibly displaced to the oblique dispensing position by the improper object 61, the dispensing solenoid 39 is demagnetized and the ball is fed by the regulating piece 41. The body 37 is in a non-rotatable state, and subsequent payout of the stored balls is restricted, so that only one or two balls at the upstream portion of the payout path 30 can be withdrawn.

It should be noted that the switching valve 52 due to the unauthorized object 61
As one of the operation setting conditions of the dispensing solenoid 39 for the illegal operation of the user, one illegal ball removing operation (the maintenance switch 6)
In the case where the solenoid 39 is set to be deactivated only by turning on (5 → ON → OFF), if the unauthorized operation by the unauthorized object 61 is released, the switching valve 52 is operated under the operation of the switching solenoid 48. The swing cam 54 returns to the upright return position, and accordingly, the rotating cam 54 turns the maintenance switch 65 ON. However, even if the maintenance switch 65 is turned on, the dispensing solenoid 39 does not operate, so that it is impossible to withdraw the ball to the ball ejection path 9 side. It cannot be withdrawn to the first prize ball path 5 side.

Further, as an operation setting condition of the dispensing solenoid 39, after the N times (for example, three times) illegal ball removing operations (ON to OFF of the maintenance switch 65), the solenoid 39 is set.
Is set to stop the operation, the switching valve 5 is released if the first unauthorized operation by the unauthorized object 61 is released.
2 swings back to the upright return position under the operation of the switching solenoid 48, and accordingly, the rotating cam 54 turns the maintenance switch 65 ON. That is, the maintenance switch 65
Becomes the condition for detecting the switching valve 52, the switching solenoid 48 resumes its operation, and the withdrawal of the stored balls to the return path 31 and the ball removal path 9 is started.
(See FIG. 12 (b)). Then, from the supply port 6, the first prize ball path 5
If the illegal object 61 that has entered the inside is again brought into contact with the switching valve 52 and rocked, the maintenance switch 65 is turned off, and the condition that the switching valve 52 is not detected is established, and the dispensing solenoid 39 is demagnetized. Then, the payout of the stored balls is stopped. Therefore, even in the second illegal ball removing operation,
Only one or two balls located upstream of the payout path 30 can be removed. Similarly, in the third illegal operation, only one or two balls can be extracted. Therefore, only a few stored balls can be extracted by the third illegal operation. In addition, when the set number of illegal operations are performed on the payout solenoid 39, the next ball-pulling detection signal is set to be valid input based on the input condition of the reset switch 60. .

In this embodiment, the case where the "a contact" is used as the maintenance switch 65 has been described. However, when the switch button 66 is not pressed, the switch button 66 is maintained in the ON state. It is possible to use a “b contact” that is turned off only while the button 66 is pressed. In this case, the switch 65 is set to detect the return position of the switching valve 52 in the OFF state.

As described above, according to the prize ball discharging device of the pachinko gaming machine according to the present invention, the ball that performs the payout operation of the ball in one case set on the mechanism set board on the back side of the machine. The incorporation of the dispensing unit and the switching discharge unit for performing a ball discharge switching operation makes the entire apparatus 1
There is an advantage that the device can be handled as a unit member for each case body, and the device can be reduced in size and simplified. Moreover, when assembling to the mechanism set board, simply positioning the case body at a required portion of the mechanism set board and assembling it with screws or the like, the ball dispensing section and the switching discharge section are properly positioned in the ball processing section. The pachinko gaming machine can be easily and easily disposed, and the member can be simplified, and the assembling operation of the pachinko gaming machine can be rationalized.

Further, according to the prize ball discharging device in the pachinko gaming machine according to the present invention, the switching valve held at the return position by the maintenance switch disposed in the switching discharging portion can be detected, and the switch is provided. The ball payout unit is configured to operate based on the detection input. In other words, under the condition that the switching valve is held at the original return position and the maintenance switch is detected, the ball dispensing section can be operated to discharge the stored ball as a return ball to the outside of the machine. Under the non-detection condition of the maintenance switch due to being displaced to the payout position side, it is possible to stop the ball payout portion and to make it impossible to pay out the stored balls. Therefore, even if, for example, an illegal object can be introduced into the prize ball path from the supply port communicating with the upper ball tray and the switching valve can be held at the dispensing position while being skillfully manipulated, the switching valve is not at the return position. The maintenance switch is set to the non-detection condition, and there is an extremely beneficial effect of stopping the ball dispensing section to prevent illegally obtaining the illegally withdrawn stored ball.
